Mistress Eva owed this guy money and she knew he was a loser. She did not want to give him money because she felt she had something better than money to give him. She could tell he had never had the attention of a woman and especially a fine one like her so she felt that was better than the money she owed him. So she gave him her time and also allowed him to lick her feet and her socks in exchange for what she owed him.
